Handling input with the Zend Framework (Post,get,etc)

Question

im re-factoring php on zend code and all the code is full of $_GET[\"this\"] and $_POST[\"that\"]. I have always used the more phpish $this->_

Answer 1

I usually use $this->_request->getParams(); to retrieve either the post or the URL parameters. Then I use the Zend_Filter_Input to do validation and filtering. The getParams() does not do validation.

Using the Zend_Filter_Input you can do application level validation, using the Zend Validators (or you can write your own too). For example, you can make sure the 'months' field is a number:

$data = $this->_request->getParams();

$validators = array(
    'month'   => 'Digits',
);

$input = new Zend_Filter_Input($filters, $validators, $data);
